2018 Lexus NX Common Problems by Component
36 owner complaints grouped by vehicle system.
SERVICE BRAKES
4 complaintsSafety-relatedOwners of the 2018 Lexus NX report issues with the service brakes, often describing brake failure during operation. Complaints frequently mention the brake pedal going to the floor and brakes being unresponsive, sometimes leading to unintended acceleration. Two incidents involve crashes, with one resulting in a minor injury. The problems are noted at varying mileages, including around 17,000 and 40,000 miles. These reports indicate potential safety risks, such as loss of vehicle control and collisions, which prospective buyers should consider.
FUEL/PROPULSION SYSTEM
3 complaintsOwners of the 2018 Lexus NX frequently report issues with the fuel pump, leading to repeated failures and vehicle stalling. Typical symptoms include the activation of warning lights such as the check engine and traction control lights, followed by the vehicle entering limp mode and ultimately stalling. These issues often occur without prior warning and can happen at high speeds, as reported by owners experiencing stalls on highways. Complaints suggest these problems arise even after fuel pump replacements, with one owner noting incidents around 144,400 miles. The potential for sudden loss of power poses safety risks, especially in high-speed traffic situations. Some owners express frustration over their vehicles not being included in existing recalls despite experiencing similar symptoms.
UNKNOWN OR OTHER
3 complaintsOwners of the 2018 Lexus NX report issues primarily related to unexpected dashboard warnings and abnormal noises. One owner describes a sudden dashboard warning indicating a need for service, accompanied by stalling and hesitating while driving, which was later linked to a fuel pump recall. Another owner reports persistent abnormal noises and clunking sounds from the front driver side, particularly when braking or turning the steering wheel, which the dealership attributes to normal fuel movement. Additionally, one complaint highlights concerns about the reverse camera functionality in 2018 models, contrasting it with improvements made in 2019. These issues are reported across varying mileage ranges and can impact vehicle safety, particularly if related to braking or camera functionality.
ELECTRICAL SYSTEM (3 complaints)
ELECTRICAL SYSTEM
3 complaintsOwners of the 2018 Lexus NX report issues related to the electrical system, with two primary problems emerging. Multiple owners describe incidents where the vehicle's engine unexpectedly stalls, occurring both shortly after purchase and over extended use, potentially posing a safety risk due to loss of power while driving. Additionally, one owner reports a side mirror unexpectedly detaching with exposed wires, raising concerns about component durability. These issues have been noted at varying mileages, with some occurrences happening shortly after the vehicle is acquired. Safety implications include potential accidents due to sudden engine stalling and mirror detachment.
FUEL SYSTEM (2 complaints)
FUEL SYSTEM
2 complaintsOwners of the 2018 Lexus NX report issues related to the fuel system, particularly involving the fuel pump and fuel hose. One owner describes a situation where the vehicle stalled at high speed, with warning lights indicating a potential fuel pump failure, occurring around 232,000 miles. Another owner reports a significant fuel leak caused by a torn fuel hose, possibly due to external damage, at approximately 30,000 miles. These issues could pose safety risks, such as stalling at high speeds or fuel leaks, which might lead to fire hazards. Buyers should be aware of these potential fuel system problems, especially when considering vehicles with high mileage.
STEERING (2 complaints)
STEERING
2 complaintsOwners report two distinct issues with the 2018 Lexus NX related to steering. One complaint describes a malfunctioning steering wheel that becomes difficult to maneuver, posing a risk if the driver cannot handle the wheel effectively during turns. This issue reportedly began in March 2022 and has worsened over time, with no resolution from dealership inspections and no warning indicators present. Another complaint highlights severe shaking and temporary loss of power while driving, linked to a fuel pump defect, although this is primarily related to engine performance rather than steering. Safety implications include potential loss of vehicle control due to steering difficulties, especially if the problem persists without visible warnings or dealership acknowledgment. Buyers should be aware of these reported issues when considering this vehicle.
STRUCTURE (2 complaints)
STRUCTURE
2 complaintsOwners of the 2018 Lexus NX report issues related to the vehicle's structure, specifically with the bottom door panels and interior door beam. One complaint describes the driver's side interior beam as having a dent-like appearance, raising concerns about its ability to provide adequate protection in a side impact, though no accidents have been reported. Another owner notes that the bottom door panels accumulate excessive dirt and snow, and the rear door collects dirt in the gap between the wheel arch trim and the door. These issues primarily relate to the vehicle's design and do not specify any mileage range or timeline. Safety concerns are primarily associated with the potential impact protection of the driver's side door beam.
VISIBILITY/WIPER (1 complaints)
VISIBILITY/WIPER
1 complaintWhile driving regularly on the highway my sunroof spontaneously shattered. There were no warning signs and no visible debris on the road that could have hit it. This is the SECOND instance of this happening with this vehicle (2018 Lexus NX 300) within three years. The sudden loud sound is dangerous as it can cause someone to jerk the steering wheel. Also, if the sunroof is open, glass could rain down on the occupants of the vehicle. My sunroof was closed at the time, but my vehicle littered glass over the roadway while trying to exit safely. The dealership refuses to take responsibility for the manufacturing defects in their sunroofs.
ENGINE (1 complaints)
ENGINE
1 complaintHVAC Evaporator Drain Hose keeps getting clogged resulting in the overflow of water into the cabin driver side floor. When using the AC or Defroster this could be a quart of water or more which can result in mold/mildew on carpet and pad. Lexus wants $6000 to repair and replace (they will not repair with out replacing all of the carpet and pad). This is a known issue and Lexus have even issued a "fix" AT THE CONSUMER EXPENSE. https://static.nhtsa.gov/odi/tsbs/20...31864-9999.pdf If a recall were issued for the recommended part (ARINIXTip) to be installed then the consumer could save thousands of dollars for the replacing of carpet and pad plus labor.

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
Get notified when new recalls or reliability data is added for the Lexus NX.
